A New Method of Detecting Steganography by using LSB Technique

Abstract

“Steganography†is a Greek origin word which means “hidden writingâ€. Steganography word is classified into two parts: Steganos which means “secret or covered†(where you want to hide the secret messages) and the graphic which means “writing†(text). Steganography is the art or science of concealing the existence of data within an ordinary and inconspicuous medium or host, steganalysis is the art of detecting the hidden messages embedded in digital media using- Steganography, The LSB (Least Significant Bit) of a file is the last bit (technically speaking, it is the first) in an 8-bit byte, which modifies the value of the byte by only 1 if changed. ITiis paper focuses on the techniques of Least Significant Bit (LSB), Embedding using digital images as a medium. The terminology is that a message is hidden within a cover image to produce a stego-image. In this paper, a new method is presented, implemented and analyzed.
